10. PHP扩展模块安装
PHP扩展模块安装
下载安装redis
redis 在LAMP下，被当作缓存来使用！
1. 下载并切换到指定目录：
cd /usr/local/src/
wget https://codeload.github.com/phpredis/phpredis/zip/develop
mv develop phpredis-develop.zip //改名
unzip phpredis-develop.zip//解压缩
cd phpredis-develop
2. 生成configure：
/usr/local/php7/bin/phpize //生成configure文件
有时候安装会出错，缺少一个包autoconf
# yum install -y autoconf
重新生成configure
# /usr/local/php7/bin/phpize
Configuring for:
PHP Api Version: 20160303
Zend Module Api No: 20160303
Zend Extension Api No: 320160303
3. 编译配置：
# ./configure --with-php-config=/usr/local/php7/bin/php-config
4. 安装测试：
make
make install
ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
opcache.soredis.so
然后就会有redis.so这个插件！这就是我们需要的扩展模块
# make install
Installing shared extensions: /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
# ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
opcache.soredis.so
5. 查看php是否支持redis：/usr/local/php7/bin/php -m |grep redis
# /usr/local/php7/bin/php -m
bz2
Core
ctype
date
dom
exif
fileinfo
filter
gd
hash
iconv
json
libxml
mbstring
mcrypt
mysqli
openssl
pcre
PDO
pdo_mysql
pdo_sqlite
Phar
posix
Reflection
session
SimpleXML
soap
sockets
SPL
sqlite3
standard
tokenizer
xml
xmlreader
xmlwriter
zlib
不支持，找到模块路径
# /usr/local/php7/bin/php -m |grep redis
6.查找extension_dir,查看扩展模块存放目录，我们可以在php.ini中去自定义该路径
# /usr/local/php7/bin/php -i |grep extension_dir
extension_dir => /usr/local/php7/lib/php/extensions/no-debug-zts-20160303 => /usr/local/php7/lib/php/extensions/no-debug-zts-20160303
sqlite3.extension_dir => no value => no value
7.手动添加模块
# vim /usr/local/php7/etc/php.ini
搜索 /extension
extension = redis.so
# vim /usr/local/php7/etc/php.ini
# /usr/local/php7/bin/php -m |grep redis
redis
2.编译自带的PHP源码包
实际上在php7的源码包中，有很多自带的源码包。我们不需要再次下载，直接编译即可！
# cd /usr/local/src/php-7.1.6/
# cd ext/
# ls
bcmath fileinfo libxml pdo_firebirdsession tidy
bz2 filter mbstring pdo_mysql shmop tokenizer
calendar ftp mcrypt pdo_oci simplexmlwddx
com_dotnet gd mysqli pdo_odbc skeleton xml
ctype gettext mysqlnd pdo_pgsql snmp xmlreader
curl gmp oci8 pdo_sqlite soap xmlrpc
date hash odbc pgsql sockets xmlwriter
dba iconv opcache phar spl xsl
dom imap openssl posix sqlite3 zip
enchant interbasepcntl pspell standard zlib
exif intl pcre readline sysvmsg
ext_skel json pdo recode sysvsem
ext_skel_win32.phpldap pdo_dblibreflection sysvshm
然后我们会发现有很多自带的源码包，
1. 首先我们先确认一个zip包，
# /usr/local/php7/bin/php -m |grep zip
# cd zip/
# ls
config.m4 CREDITS lib php_zip.ctestszip_stream.c
config.w32examplesLICENSE_libzipphp_zip.hTODO
2.假如我们需要编译一个zip，首先进入zip目录。 然后输入：
# /usr/local/php7/bin/phpize
Configuring for:
PHP Api Version: 20160303
Zend Module Api No: 20160303
Zend Extension Api No: 320160303
# ./configure --with-php-config=/usr/local/php7/bin/php-config
3.make;make install
# make install
Installing shared extensions: /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
# ls /usr/local/php7/lib/php/extensions/no-debug-zts-20160303/
opcache.soredis.sozip.so
